in this case one could argue, that you should ensure the padding manually :)
That seems counter-intuitive to me. If you expect users to do so that should probably be spelled out clearly.
well, i think this is not really a common case. if one wants to be sure, that there is absolutely no false sharing, one would have to pad the whole class to ensure that nothing before and nothing after the data structure will be placed in the same cache line. but i think going that far is overkill ...
Interesting -- I would have expected this to be the common case and the cost of cacheline alignment to be relatively minor for a ringbuffer. Anyway, I'll see if I can take a closer look.
